To obtain basic information on the utilization of Suaeda (S.) asparagoides $M_{IQ}$ as a raw material in food, it's chemical components of were investigated. S. asparagoides $M_{IQ}$ from the Hwaseong-si in Korea was used after drying and grinding with powder. The total dietary fiber, insoluble dietary fiber and soluble dietary fiber contents of S. asparagoides $M_{IQ}$ were found to be 39.41%, 37.63% and 1.78%, respectively. Macromineral components of S. asparagoides $M_{IQ}$ were Na (7.6%), K (2.4%) and Mg (0.6%). High contents of microminerals such as Cu, Mn and Zn were also found. Lysine and methionine which are essential amino acids were detected with the value of 215 mg/100 g and 23.2 mg/100 g, respectively. S. asparagoides $M_{IQ}$ that was harvested in May was higher in crude protein than that harvested in September but the crude fat content of that which was harvested in September was twice as high as that harvested in May.

The study was conducted to evaluate the effect of substitution of flour with Suaeda asparagoides(at the levels of 0%, 2%, 4%, and 6%) on the characteristics of sponge cake. The specific gravity of batter increased significantly as the content of Suaeda asparagoides increased. The specific volume and baking loss rate of cake decreased significantly as the content of Suaeda asparagoides increased. The volume and weight of batter increased significantly as the content of Suaeda asparagoides increased. Texture analysis showed that the control had the lowest hardness and highest springiness. According to sensory evaluation, the experiment groups scored higher points in texture acceptance than the control. Above all, the 2~4% samples scored the highest points in aroma, taste, appearance, and overall acceptance.

To investigate the environmental adaptation and ecophysiological characteristics of Suaeda maritima and S. asparagoides under saline conditions, plant growth and density were analyzed according to environmental changes of habitats. The total ion content of soil decreased with time, which was caused by the predominance of exchangeable $Na^+$ and $Cl^-$ in the upper layers. The population of S. maritima was more densely distributed in the region with higher ion contents of $Cl^-$, $Mg^{2+}$, $K^+$ and $Na^+$ than the population of S. asparagoides. Both species were showed a decreased population density according to increases in plant growth. Under the conditions of a salt field, S. maritima and S. asparagoides contained high inorganic ions to maintain low water potential, but low water soluble carbohydrate contents. In the case of free amino acid, S. maritima showed an especially high proline content, and contained rather large amounts of free amino acids, whereas S. asparagoides did not. Both species showed high inorganic ion contents in the leaves, which might be a mechanism of avoiding the ionic toxicity by diluting the accumulated ionic concentration with a high ratio of water content to dry weight. This result suggests that S. maritima seems to adapt to saline conditions by accumulating proline in addition to inorganic ions. S. asparagoides seems to adapt by osmoregulation processes, using inorganic ions rather than free amino acids.

Suaeda asparagoides (Miq.) is a salt marsh plant, long been prescribed in traditional medicine for the treatment of hypertension and liver toxification in Asian countries. The powder of S. asparagoides was added at the ratio of 0, 5, and 10%, respectively, of grain-type Meju to manufacture Doenjang in brine according to the salt concentration (8 and 12%). After 24 weeks of fermentation, the Doenjang samples were determined to have an anti-inflammatory effect on RAW 264.7 cells. Evaluation of the anti-inflammatory effect of Doenjang added S. asparagoides powder extracted using 80% EtOH, was performed to study the inhibition of pro-inflammatory factors such as NF-κB (nuclar factor κB), NO (nitric oxide), TNF-α (tumor necrosis factor alpha), IL-6 (interleukin-6), iNOS (inducible nitric oxide synthase), and COX-2 (cyclooxygenase-2) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. The results showed that the Doenjang extracts reduced the production of NO, IL-6, COX-2, and iNOS increased in the LPS-stimulated RAW cell without cytotoxicity. In the case of the NF-κB and TNF-α there was no significant difference between the control and samples. In conclusion, these results suggest that Doenjang added with the S. asparagoides powder acts as functional fermented food with anti-inflammation effect.

Suaeda (S.) asparagoides $M_{IQ}$, one of the halophyte groups, has been used as a folk remedy for digestive disturbances in Korea. However, its pharmacological activity on gastrointestinal motility has not been reported yet. In this study, the effects of this halophyte extracts with various solvent fractions (ethanol, hexane, chloroform, ethyl acetate, butanol, and water) on mice ileal spontaneous motility was examined. All solvent fractions at the concentration of $100{\mu}g/ml$ showed inhibitory actions on spontaneous motility of ileum with the potency order of water > 70% ethanol > hexane ${\gg}$ chloroform ${\geq}$ butanol ${\geq}$ ethyl acetate, respectively. In addition, the water fraction of extracts from S. asparagoides $M_{IQ}$ (WFSA) dose-dependently ($1-100{\mu}g/ml$) inhibited the amplitude of spontaneous phasic contraction and area under the contractile curve (AUC). The inhibitory effect of water fraction at the concentration of $10{\mu}g/ml$ was not affected by tetrodotoxin (TTX), $Na^+$ channel blocker ($1{\mu}M$), and $N^w$-nitro-L-arginine Methyl Ester (L-NAME), nitric oxide synthase inhibitor ($100{\mu}M$). However, cyclopiazonic acid (CPA, $10{\mu}M$), inhibitor of sarcoplasmic reticulum $Ca^{2+}$-ATPase, almost blocked the inhibitory effects of WFSA ($10{\mu}g/ml$) on the spontaneous phasic contraction of mouse ileum. But, CPA did not inhibit the lowering basal tone effects of WFSA. The result of this study showed that various extracts of S. asparagoides $M_{IQ}$ induce inhibitory effects on spontaneous contraction of mice ileal segments. More over, the polar solvent fractions were shown to be more potent than non-polar solvent fractions. The effects of S. asparagoides $M_{IQ}$ extracts are not mediated by nerve or nitric oxide. The inhibitory effects of WFSA at least partially mediated by sarcoplasmic reticulum $Ca^{2+}$-ATPase. However, further study is required to determine the exact pharmacological mechanisms of this halophyte on its gastrointestinal motility inhibitory effects.

South Korea is largely dependent on imports of forage crops. In order to raise the self-sufficiency rate of forage crops, it is necessary to cultivate forage crops in 135,100 ha reclaimed land of South Korea. This study was conducted to investigate the growth of halophytes and forage crops in order to search for stable plants on reclaimed land. The plants were cultured in Hoagland solution and grown at 0%, 0.5%, 1.0% and 2.0% of salt concentrations. Plants with good growth at 0.5% of salt concentration were halophytes such as Suaeda asparagoides and Salsola komarovii. Salicornia herbacea and Suaeda maritima showed good growth at 2.0% salinity, and Suaeda maritima showed stable growth at all of salt concentrations. In conclusion, Suaeda asparagoides showed the best growth at 0.5% of salt concentration and was considered the most biomass at reclaimed land in Korea with less than 0.5% of salt concentration.

A study on vegetation in the Mangyeong River and Dongjin River basins and the surrounding regions of the Saemangeum Reclaimed Land was conducted in a series of efforts to determine the expected ecological changes in the salt marshes, to restore their vegetation, to explore the restoring force of halophyte, to examine the community mechanism and, ultimately, to rehabilitate marshy land vegetation along the lakeside, coastal dune and salt marshes of the Saemangeum Project Area. The findings of the study may be summed up as follows: Five species such as Suaeda japonica, Salicornia herbacea, Atriplex gmelini, Aster tripolium and Suaeda asparagoides that are mostly distributed in the estuary of the Saemangeum Reclaimed Land were analyzed to examine the mechanism of halophyte to maintain their community. To find out the strategies of plants for survival and the cause of forming community structure, a research was made as for appearance ratio of young sapling. From the results of laboratory analysis into dynamics of the saplings of halophyte, it was revealed that the germination ratio of the dry area and submerged area decreases in the order of Suaeda asparagoides, Suaeda japonica, Salicornia herbacea, Atriplex gmelini and Aster tripolium.

The germination period, the germination under different saline concentration and temperature condition, the survival percent several halophytes in cross-transplanting experiment of marsh type and the soil environment factor of five dominant species were investigated on the halophytes population formation strategies on the salt marsh of Mankyeong river estuary from February to October 2005. In terms of germination, Suaeda japonica appeared first followed by Aster tyipolium Salicornia herbacda, Atriplex gmelini and Suaeda asparagoides. The germination percent on the humidify conditions and saline concentrations of halophytes were that Suaeda japonica germinated well under inundation conditions, high temperature and low salinity; Salicornia herbacda under high salinity; Aster tripolium and Atriplex gmelini under dry or inundation conditions, and Suaeda aspar agoides under dry conditions and high salinity. The survival percent in cross-transplanting experiment of five halophytes were high with Suaeda japonica in the low marsh; Salicornia herbacda, Aster tripolium and Atriplex gmelini in the mid marsh, Suaeda asparagoides in the high marsh. The soil properties were similar for the five halophytes, but soil texture appeared high in order of silt, sand and clay. These results suggested that population formation strategies of five halphytes. Suaeda iaponica was distributed in the low tidal marsh, Salicornia herbacda, Aster tripolium, Atriplex gmelini in the mid tidal marsh and Suaeda asparagoides in the high tidal marsh.
